Oh, good grief! I meant to warn, of course, about 'benzene', the famous C6H6 ring molecule, not 'benzine'. I blame my age - old enough to know how, too old to do...
I have an irritating ability, or handicap: typos, etc. tend to leap out of the page at me. I grumble about the lack of proof-reading, misspelling, errant apostrophes, etc. that is so common, nowadays. But, of course, I'm oblivious to my own mistakes...
Just to add to the confusion, I now discover that there's something called 'petroleum benzine' (sic), probably what 'wasbenzine' is, which also isn't the unique chemical compound 'benzene'. It seems that you can bung any name you like on a mix of light fractions of petroleum distillate, flog it as a solvent, fuel, magical do-all, and an answer to a maiden's prayer, and it's accepted by everyone except miserable pedants like myself.
